Generally speaking, the engineers put a lot of thought into the design of the intake tract.
the metal CIA's CRACK ME UP.. its a metal pipe under your hood.. even if the filter is inside the fenderwell, its still draggin cool air through a hot pipe !.. then, most of the time CAI'S piping is the same size or smaller than the factory oversized ductwork.
in my younger years i tried two different CIA's a expensive K&N setup that was plastic and the filter was inside the doghouse, and a metal Ebay specail that was $75 and was metal- crome with some china knock-off filter in the fenderwell.
they both made my stangs induction louder.. and thats it.. i noticed nothing else, no noticable MPG increase, no power increase (and as a matter of fact i did have my Mustang dyno'd) The only positive i experienced was the Metal CIA made a easy spot to drill into for my dry NOS system.. NOW that made a HP difference. I coulda tapped into my factory plumbing but the crome CIA looked much cooler when i was 25.
